Description

[Detailed Description of the Invention] The present invention relates to a device that generates a sound effect (tick-tock sound) in an electromagnetically driven pendulum used as a swinging decoration of a clock.

In recent years, pendulums are often driven electromagnetically, but such electromagnetically driven pendulums do not generate ticking sounds. From a general concept, it is normal to hear a ticking sound in a pendulum clock, so users sometimes felt strange when using an electromagnetically driven pendulum. Therefore, Utility Model No. 145383 was developed using an electromagnetically driven pendulum that produced a sound effect similar to the tick-tock sound of the old Ankle Gangi type pendulum. On the other hand, some users say that it is better not to have the ticking sound when going to bed because it interferes with their sleep.

Therefore, the present invention allows the user to select whether or not to generate sound effects according to his/her preference, and one embodiment thereof will be described below.

In Figures 1 and 2, a swinging rod 1 has a support shaft 2 at its upper end, and an inverted V-shaped swing receiving part 3 is formed downward on this support shaft 2, and is installed at a fixed position. It is designed to be swingably supported on a knife edge stand 4. A hook portion 5 is integrally formed at the lower end of the swinging rod 1 , and a ball rod 7 of a swinging ball 6 is removably hooked to the hook portion 5. A box-shaped holder part 8 is formed above the hook part 5, and a drive magnet 9 is fitted and fixed to this holder part 8, and this drive magnet 9 is fixedly installed in front of the drive coil (not shown). ), thereby causing the swinging rod 1 to swing at a constant period. Further, an opening window 1 is provided above the holder part 8.
0 is opened, and its lower side is a roughly V-shaped support part 1.
It's becoming 1.

The piece body 12 inserted into the aperture window 10 is smaller than the aperture window 10 and has a substantially inverted triangular shape, and the width of its upper end is smaller than that of the aperture window 10. Rectangular plate-shaped spring parts 13, 13 are integrally formed upwardly extending from both sides of the upper end of the bridge body 12, and protrusions 14, 14 are formed so as to face each other at the tips thereof. Further, position regulating portions 16, 16 are formed to hang down on both sides of the lower edge portion 15.

This piece 12 can be inserted into the opening window 10 by the following procedure. First, insert the piece body 12 into the opening window 10.
Hold it next to the spring part 13, 13.
The upper edge 17 of the opening 10 between the protrusions 14, 14
Insert and push upward. Then piece body 12
The lower part of the piece no longer catches on the lower side of the opening window 10, and the piece body 12 can stand vertically within the opening window 10. If the piece 12 is lowered here,
The lower edge portion 15 will be placed on the support portion 11, but when the piece body 12 is lifted upwards, a horizontal protrusion is formed on both sides above the upper edge portion 17 of the opening portion 10. The locking part 18 is connected to the spring part 1
The protrusions 14, 14 of 3 and 13 climb over and the 1st to 2nd
Lock the bullet as shown. At this time, the upper end surface of the piece 12 is held in close contact with the upper edge of the opening window 10. Therefore, in the states shown in the first and second figures, the piece body 12 cannot move or move relative to the swinging rod 1 when the swinging rod 1 swings. In other words, the swing rod 1 and the piece body 12
move as one, no different from conventional pendulum motion, and therefore no sound effects are generated.

When the piece body 12 is pulled down from the state shown in FIGS.
The opening window 10 is placed between the protrusions 14, 14.
The upper edge 17 of is now located. (3rd to 4th
(See figure) The distance between the protrusions 14, 14 is the upper edge 17.
The thickness of the piece 12 is set to be slightly larger than the thickness of the piece 12, so that the piece 12 is held rotatably about its lower edge portion 15 as a swinging fulcrum. Now, when the swinging rod 1 swings to the left as shown in the third figure, the center of gravity of the piece body 12 shifts to the right side of the support part 11 (lower edge part 15), and the piece body 12 suddenly moves due to the action of gravity. It rotates to the left and its upper left end collides with the left side surface of the opening window 10. In this way, when the bridge body 12 alternately collides with both sides of the opening window 10 in synchronization with the movement of the swinging rod 1 , a collision sound is generated, and this sound is similar to the escapement of an ankle escapement. It sounds like a ticking sound.

As described above, according to the present invention, the protrusions 14, 14 of the spring parts 13, 13 of the bridge body 12 are connected to the locking parts 18, 1.
Depending on whether or not the pendulum hits 8, the pendulum will operate silently or with sound effects, and the user can choose according to his or her own preference.
The selection operation is also easy. In addition, since the structure is simple, manufacturing and assembly are easy and can be carried out at low cost.

Claims (1)

[Claims for Utility Model Registration] An opening window is formed in a part of an electromagnetically driven swinging rod, and a piece body that is inserted into the opening window and is smaller than the opening window and has a substantially inverted triangular shape. a substantially V-shaped support portion for rotatably supporting the lower end of the piece is formed at the lower side of the opening window, and a pair of springs extending upward from both sides of the upper end of the piece. protruding parts are formed integrally with the tips of the two spring parts, projecting parts are formed oppositely on the tips of the spring parts, locking parts are formed protruding on both sides above the upper edge of the opening window, and the lower end of the piece body When the is in contact with the support part, the upper edge of the opening window comes into play between the two protrusions, and the piece body rotates in synchronization with the rocking movement of the swinging rod. The piece body collides with both side edges of the opening window to generate a sound effect, and by lifting the piece body upward, both of the protrusions impact the locking part, A sound effect generating device for an electromagnetically driven pendulum, characterized in that the piece body is thereby held unrotatable relative to the swing rod.
